Forest Therapy connects people with nature, to the benefit of both. Also known as "Shinrin-Yoku," Forest therapy refers to the practice of spending time in forested areas for the purpose of enhancing health, wellness, and happiness. The practice follows the general principle that it is beneficial to spend time bathing in the atmosphere of the forest. The Japanese words translate into English as “Forest Bathing.” Although we are inspired by the Japanese practice our use of the terms Forest Therapy and Shinrin-Yoku do not mean a specifically Japanese practice. We mean spending time in nature in a way that invites healing interactions. There is a long tradition of this in cultures throughout the world. It’s not just about healing people; it includes healing for the forest (or river, or desert, or whatever environment you are in).
